Jumper 2.0 is enterprise web-infrastructure for tagging and linking information resources.[5] Jumper 2.0 lets you search and share high-value content, media, or data across remote locations using knowledge tags to capture knowledge about the information in distributed storage. It collects these tags in a tag profile. The tag profiles are stored in an interactive knowledge base and search engine.

The software represents a fundamentally new approach to searching structured and semi-structured data using a Web 2.0 front-end where user-created tag profiles bookmark quality information resources, user contributed experiences add real-world knowledge about the information resources, and user-created reviews sort out the worthy resources from the inadequate[6]

Jumper 2.0 is free software under the GPLv2 license. Users can purchase installation and support contracts under commercial, educational, or nonprofit licenses.[7]

Users access Jumper 2.0 via any industry standard browser. The Search Engine in Jumper is the first thing users see when they access the Jumper Intranet portal. Access to Jumper can be open to the public or controlled by requiring log-in to view some or all of the tag profiles. By clicking on a search result users can view the full tag profile. The ‘tag profile’ is a reference to an information resource located in a remote storage device. The tag profile captures knowledge about this resource using social tagging. The full tag profile is returned with the search results. Much like a card in a card catalog it is a central reference point to collect and discover information associated with and about distributed information resources. With certain privileges a user can add a comment to the tag profile, expand upon the description, add new knowledge, or link the profile to another information resource. In addition, viewers can rate the value, accuracy or completeness of the tag profile. They can also choose to create a new tag profile that references content, media, or data regardless of format or location.

Jumper was originally created as a project for the Sun MicrosystemsJini Community.[8] The software was first presented at the 6th annual JCM Sessions.[9] Project Jump created a name server storing persistent names for data objects using a system of "natural language addressing" based on descriptive metrics, which have since been adopted by JXTA.[10] It was originally developed by Steve Perry from his work as a data integration consultant.

The Jumper Open Source Project is a community effort, led by Jumper Networks, devoted to building and maintaining the open source version of Jumper.[11]

Jumper Networks Inc., the company that provided commercial support for the Jumper Collaborative Search Engine, and the related company website were closed in September 2011.
